Genes affected
SEC16A (HGNC:29006): (SEC16 homolog A, endoplasmic reticulum export factor) This gene encodes a protein that forms part of the Sec16 complex. This protein has a role in protein transport from the endoplasmic reticulum (ER) to the Golgi and mediates COPII vesicle formation at the transitional ER. Alternative splicing results in multiple transcript variants that encode different protein isoforms. [provided by RefSeq, Feb 2013]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 29, 2024The c.6937G>A (p.D2313N) alteration is located in exon 31 (coding exon 29) of the SEC16A gene. This alteration results from a G to A substitution at nucleotide position 6937, causing the aspartic acid (D) at amino acid position 2313 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
